The Impact of Raising the Bar for Clinical Trials in Ulcerative Colitis.

J Crohns Colitis 2019 Feb 14. Epub 2019 Feb 14.

University of Michigan, Ann Arbor, MI, USA.

In order to identify the practical implications for both health care practitioners and patients in understanding differences between the results of trials assessing therapies for ulcerative colitis [UC], we reviewed clinical trials of therapies for moderate to severe UC, with a focus on trial design. Over time, patient populations in UC trials have become more refractory, reflecting that patients are failing treatment with additional and different classes of drug, including conventional therapies, immunosuppressant drugs, and anti-tumour necrosis factor therapies. Outcomes used to measure efficacy have become increasingly stringent in order to meet the expectations of patients and physicians, and the requirements of regulatory bodies. Read More

Confocal Laser Endomicroscopy in the Evaluation of Inflammatory Bowel Disease.

Authors:
Anna M Buchner

Inflamm Bowel Dis 2019 Mar 16. Epub 2019 Mar 16.

Division of Gastroenterology at University of Pennsylvania, Philadelphia, Pennsylvania.

Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, can be effectively monitored with the use of endoscopy. The additional application of small field imaging technology such as confocal laser endomicroscopy CLE during ongoing endoscopic evaluation has led to real-time visualization of mucosal abnormalities and thus in vivo histology. The endomicroscopy (CLE) can improve IBD endoscopic evaluation by identifying seemingly normal-appearing mucosa, assessing the function of the intestinal barrier of the epithelium and vascular permeability, and by characterizing any mucosal lesions, including dysplastic lesions.

Contraception, Venous Thromboembolism, and Inflammatory Bowel Disease: What Clinicians (and Patients) Should Know.

Inflamm Bowel Dis 2019 Mar 16. Epub 2019 Mar 16.

Section of Gastroenterology, Boston Medical Center, Boston, Massachusetts.

The peak incidence of the inflammatory bowel diseases (IBDs) is between the second and fourth decades of life, which coincides with prime reproductive years. Unplanned or mistimed pregnancies may account for nearly half of all pregnancies and are associated with adverse consequences such as a higher risk of delayed preconceptual care, increased risk of preterm birth, low birth weight, and adverse maternal and neonatal outcomes. Increased IBD activity during pregnancy is also associated with adverse pregnancy-related outcomes, such as miscarriage, intrauterine growth retardation, and preterm birth. Read More

Intestinal microbiome as a novel therapeutic target for local and systemic inflammation.

Pharmacol Ther 2019 Mar 12. Epub 2019 Mar 12.

Molecular Gastroenterology and Hepatology, Graduate School of Medical Science, Kyoto Prefectural University of Medicine, Kyoto 602-8566, Japan; Department for Medical Innovation and Translational Medical Science, Graduate School of Medical Science, Kyoto Prefectural University of Medicine, Kyoto 602-8566, Japan.

Recently, the pathogenesis of systemic inflammatory disease such as inflammatory bowel disease (IBD), multiple sclerosis (MS), systemic inflammatory arthritis, asthma, and non-alcoholic fatty liver disease has been reported to be related to the dysbiosis of gut microbiota. The contribution of special bacteria for the development of those diseases has been elucidated by disease animal models such as germ-free mice. Besides, the contribution by several bacteria for the pathogenesis of those diseases has been suggested by detailed analysis of the 16 small ribosomal subunit RNA (16S rRNA) from stool samples of the patients.

Prediction of treatment outcome and relapse in inflammatory bowel disease.

Expert Rev Clin Immunol 2019 Mar 15. Epub 2019 Mar 15.

c Department of Gastroenterology and Hepatology , Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences , Okayama , Japan.

Introduction: Prediction of treatment outcome and clinical relapse in patients with inflammatory bowel disease (IBD), either ulcerative colitis (UC) or Crohn's disease (CD), is particularly important because therapeutics for IBD are not always effective and patients in remission could frequently relapse. Because undergoing endoscopy for the purpose is sometimes invasive and burdensome to patients, the performance of surrogate biomarkers has been investigated. Areas covered: We particularly featured the performance of patient symptoms, blood markers including C-reactive protein (CRP), fecal markers including fecal calprotectin (Fcal) and fecal immunochemical test (FIT) for prediction of endoscopic mucosal healing (MH) and prediction of relapse.

Slc26 Family of Anion Transporters in the Gastrointestinal Tract: Expression, Function, Regulation, and Role in Disease.

Compr Physiol 2019 Mar 15;9(2):839-872. Epub 2019 Mar 15.

Hannover Medical School, Department of Gastroenterology, Hannover, Germany.

SLC26 family members are multifunctional transporters of small anions, including Cl , HCO , sulfate, oxalate, and formate. Most SLC26 isoforms act as secondary (coupled) anion transporters, while others mediate uncoupled electrogenic transport resembling Cl channels. Of the 11 described SLC26 isoforms, the SLC26A1,2,3,6,7,9,11 are expressed in the gastrointestinal tract, where they participate in salt and water transport, surface pH-microclimate regulation, affect the microbiome composition, the absorption, and secretion of oxalate and sulfate, and other functions that require further study.

Rapid Downregulation of DAB2 by Toll-Like Receptor Activation Contributes to a Pro-Inflammatory Switch in Activated Dendritic Cells.

Front Immunol 2019 27;10:304. Epub 2019 Feb 27.

Department of Pediatrics, University of Arizona, Tucson, AZ, United States.

Dendritic cells (DCs) are pivotal in regulating tolerogenic as well as immunogenic responses against microorganisms by directing both the innate and adaptive immune response. In health, phenotypically different DC subsets found in the gut mucosa are maintained in their tolerogenic state but switch to a pro-inflammatory phenotype during infection or chronic autoinflammatory conditions such as inflammatory bowel disease (IBD). The mechanisms that promote the switch among the mucosal DCs from a tolerogenic to an immunogenic, pro-inflammatory phenotype are incompletely understood. Read More

Yu Zhen Hu Zhang

Front Immunol 2019 28;10:276. Epub 2019 Feb 28.

Department of Gastroenterology, West China Hospital, Sichuan University, Chengdu, China.

NLRP3 inflammasome can be widely found in epithelial cells and immune cells. The NOD-like receptors (NLRs) family member NLRP3 contains a central nucleotide-binding and oligomerization (NACHT) domain which facilitates self-oligomerization and has ATPase activity. The C-terminal conserves a leucine-rich repeats (LRRs) domain which can modulate NLRP3 activity and sense endogenous alarmins and microbial ligands. Read More

Protective effect of TSLP and IL-33 cytokines in ulcerative colitis.

Auto Immun Highlights 2019 Mar 14;10(1). Epub 2019 Mar 14.

Gut and Liver Research Center, Imam Khomeini Hospital, Mazandaran University of Medical Sciences, Sari, Iran.

Purpose: Inflammatory bowel disease (IBD) primarily includes ulcerative colitis (UC) and Crohn's disease (CD). Thymic stromal lymphopoietin (TSLP) is a cytokine produced by intestinal epithelial cells (IECs) with immunomodulatory properties that plays an important role in the development of regulatory T cell (Treg) responses and tolerance in the gut. On the other hand, IL-33 has been considered as a cytokine with two different properties, inflammatory and anti-inflammatory functions, the latter may play a protective role against chronic intestinal inflammation.

Brain-Gut Therapies for Pediatric Functional Gastrointestinal Disorders and Inflammatory Bowel Disease.

Curr Gastroenterol Rep 2019 Mar 12;21(4):12. Epub 2019 Mar 12.

Department of Medicine, Division of Gastroenterology, Icahn School of Medicine at Mount Sinai, New York, NY, USA.

Purpose Of Review: The purpose of this review is to discuss current knowledge of brain-gut therapies (BGT) in pediatric functional gastrointestinal disorders (FGID) and inflammatory bowel disease (IBD), including their evidence base, the common psychopathology that they address, and the integration of this knowledge into medical settings.

Recent Findings: Cognitive behavioral therapy (CBT), hypnotherapy (HT), mindfulness-based therapy (MBT), and exposure-based therapy (EBT) have the most data supporting their use in children, particularly in FGID, more so than in IBD. This difference is most likely because of the increased role of psychological factors in FGID, though these same factors can be seen comorbidly in IBD. Read More

Spatial and Temporal Analysis of the Stomach and Small-Intestinal Microbiota in Fasted Healthy Humans.

mSphere 2019 Mar 13;4(2). Epub 2019 Mar 13.

Department of Pharmaceutical Sciences, College of Pharmacy, University of Michigan, Ann Arbor, Michigan, USA

Although the microbiota in the proximal gastrointestinal (GI) tract have been implicated in health and disease, much about these microbes remains understudied compared to those in the distal GI tract. This study characterized the microbiota across multiple proximal GI sites over time in healthy individuals. As part of a study of the pharmacokinetics of oral mesalamine administration, healthy, fasted volunteers ( = 8; 10 observation periods total) were orally intubated with a four-lumen catheter with multiple aspiration ports.

Early-Life Nutrition and Microbiome Development.

Nestle Nutr Inst Workshop Ser 2019 13;90:151-162. Epub 2019 Mar 13.

Recent demonstrations link clinical conditions, phenotypes alternating from inflammatory bowel disease, obesity, and allergic diseases to neurodevelopmental disorders, to aberrant gut microbiota composition. This has led to a growing interest in host-microbe crosstalk, characterizing the healthy microbiome and modifying its deviations at an early age. The rationale arises from the recognition of the intimate interrelationship between diet, immune system, and microbiome and the origins of human diseases. Read More

Early-Life Nutrition and Gut Immune Development.

Nestle Nutr Inst Workshop Ser 2019 13;90:137-149. Epub 2019 Mar 13.

Gut immune function conditions the development of local and systemic diseases that result from defects in immune regulation, such as inflammatory bowel disease, allergy and obesity. As epidemiological studies support the developmental origin of health and disease, deciphering the critical factors modulating gut immune development should allow the advance of primary prevention strategies specifically adapted to the early-life immune system. Here, we will review gut mucosal immunity development and cover in more detail the recent understanding of the impact of early nutrition on this process. Read More
